Running unit tests from ccnet

I faced with a problem that VSTest.Console can not work from ccnet service. CCnet service is running from System account. If I sets log on as Administrator account for this service the VSTest.Console worked, but another programs like git - doesn't.

Is it possible to use the VSTest.Console from System account? Or maybe reconfig ccnet service?

I got following errors:

Warning: Diagnostic data adapter ('UnitTestIsolation') message: No Microsoft .NET applications were launched during the test run. Launch applications from Explorer or a new command prompt after a test case has started. If no .NET application is being tested, disable the Test Impact and IntelliTrace diagnostic data adapters..
